. l HYIDROCARBON'. MOTOR.

'To all wZLom z't may concern Beit known that I, JESSE G. VINCENT, a citizen-Of the United States, and residing at Detroit, Wayne County, State-of Michigan,

5 have invented certain new and useful Improvements. in Hydrocarbon Motors, of

which the following is a specification.

The present invention relates to' hydrocarbon motors and more particularly to such motors for airplanes.

-The. principal olijmyofY uit invention is' simplyarranged incansis employed for res 'inoving oil, of 'a capacity greater than the rate at which it is supplied. Other objectsV andjfeat'ures of novelty 'will be apparent from the description taken in' connection with the Vdrawings in .which Thesingle ligure is a longitudinal sectional View through the crank case of a hydrocarbon motor ofthe type' having twelvev cylinders arranged, in' two groups of, six

each,l one set of cylinders lining. shown in- 3o elevation, andthe oil reservoir or radiator also .being shown 1n elevation.

As shown, the uppcr'ha'lf- 10 ofthe crank.

case has the usual bearings l1, 12 and 13 for. the camshaft 14, and the bearings 15,

16, and 17 for the'crank. shaft 18;

' Each 'of-thecrank shalt braringsl, 16 and 17' has a V depending bracket 19,- 2O and 21, "respectively, secured to the caps of said bearings, and these brackets carry the pumps 4.o 22, 23 a11d24respectively, the bolts which i secure the caps being utilized tofasten thebrackets. Tli'eloiver half`25 of the crank case is formed atene end thereof with' the oil.draiii or well 26'and atf'the other end'.

wvithbasiniilar oil drain for well27, these ells receiving 'the pumps .-22 Vand|24 respc0- gtiv'ely andbeing of such shape that' there is ivory-'little clearance between the pump 'and fthe Walls of the wells.' 'lliepumps 22, '23 -nd 24. are aligned vand have the common ggiving or pump shaft 28; Under the -p'uinp @fthe lower -half of the crank case is formed Application med-January 14, 191s. semi up'. zuss.

With'a pocket 29 ivhich surrounds the portlon of the pump Whi/eh projects belowthe bottom of the cran'k'rase'. The pumps 22 and 24 are suction puinps and act to Withdraw the oil which collects in the pockets A 26 and 27 a-nddischarge it into the header which carries the oil tothe Oil reservoir. or` radiator 31. The pump 23 has a suction pipe 32 connected to the lower 'part ofthe oil reservoir and a discharge .pipe 33 connected toan oil'manifold or header 34. This header at one end is connected to discharge into `the conduit 35 in the bracket vor support 1-9 and associated bearing cap'whiehsupplies thebearing 15 and also 'the conduits 36 and. 37 formed in the crank shaft.-

The conduit 36 supplies the piston .rod-bearing 38' and the conduit 37 supplies the bear# ing for the piston rods 39 and 40. The

other end of the header 3'4 is arranged to supply' the duct 41 in the lbracket 2l and"v associated bearingcap which is connectedto oil the crank shaft bearing'l'landsupf' ply the `conduits 42 and-43 in thefcrank shaft, the conduit 43 carrying oil to the pi'sf ton rod bearing 44, and the conduit 42servj ing to deliver oil to the bearing '45.' Theis' header 34 also throughithe duct 46 in the bracket or support 20 and thev associated bearing cap Vsupplies oil'to the lbearing 16 and the conduits 47 and 48 'formed in the crank shaft, the conduit 47 carrying oil'td'f;

the bearing 49 and the conduit'43 supplyi-vv ingoil to .the bearing 50.

' The duct 4 1 vextends around the' crank shaft bearing 17 and has a continuation 51 whiclrsupplies oil to cam shaft bearino 13' and the duct 52 formed therein. This duct extends substantially throughout the length of the 'earn shaft and distributesroil to the other bearings 11 and 12 thereof. The duct i 53 formed in the wall of the crank ease above the cani shaft bearing 13 and connected therewith servest'o carry oil to the ele'ctri-4 .caldistributingapparatus" (not shown): A The -canfshar't 1s driveii from the crankv; shaft'by means ofthe chain gearing 54' and. the pump driving shaft is also driven' frein the crankshaft by a chain gearing 55.

From' the lforegoing it will Abe 'seen that-. l

the force pump 23 takes oil`from the oil reservoir and forces it to the"various bearings uf the motor. As thisoil leaves the bearings it drains.' to the small wells 26 and 27 'and the small pocket 29. Suction pumps 22v and 24, which have their suctions 56 and 57 respectively close to the bottom of the wells,

act to Withdraw substantially all of the oil at least equal to that of the force pump 23.

which hasdrained into the said Wells 26 and 27, and discharge it through the header 30 into the oil reservoir. Preferably each of :the suction pumps 22 and 24 has a capacity through'the same. It is to 'be understood,

bination,

Aducts and con however, that the invention is not limited to thlsform of reservoir as other means for storing the oil might be used. Indeed the reservoir mi ht be omitted and the oil taken from the we ls Lpumped directly to the force pump, the' con uits connecting the suction and force pumps, in this case acting as the reservoir. Y

In addition to providing a means for maintaining the crank :case of the motor substantially dry of oil, it will be observed that the pumps for accomplishing thisv p pose are arranged in a very lrigid and' yet simple manner.

'Although a specific arrangement of oil uits Vhas been .described whereby the oil is forced to the several bearings of the motor, itis to be understood that the invention is not limited to any particu. lar arrangement of the means for lubricating the bearings. Furthermore the invention is not limited to a twelve-cylinder motor, but on the other hand is adapted for use in many differentV types of hydrocarbon motors.
